GAS-BURNER.

Specification of Letters Patent.

Patented Nov. 4, 1913.

Application filed April 5, 1913. Serial N04 759,106.

To all whom it may concern Be it known that we, LOUIS C. Human and'FRANKLIN Invnve CAMP, citizens of the United States, residing atMeriden, county of New Haven, State of Connecticut, have invented anImprovement in GasBurners, of which the following is aspecification.

l he invention relates to gas burners of the type having a pilot lightfrom which the gas is automatically ignited when turned on, andparticularly to gas burners having means whereby the gas may be turnedalternately oil and on by similar successive movements of a single chainor other operating device.

One object of the invention is to provide a construction in which arelatively small movement of the valve or cockwill effectively controlthe flow of gas in the desired manner.

Other objects of the invention are to simplify and generally improvedevices of this character and to provide a self-lighting gas burnerwhich Wlll be convenient and efficient in use and otherwise wellqualified to fulfil the requirements of such a device, all as willhereinafter more fully appear.

With these and other objects in VleW we have devised the novel gasburner which we will now describe, reference being had to theaccompanying drawings forming a part of this specification, and inwhich:

Figure 1 is an elevation, partly broken away, of a gas burnerconstructed in accordance with the invention; Fig. 2 is an elevation atri ht angles to Fig. 1 with the inclosin shell removed; Fi ,3 is asection on t e line 3-3, Fig.2; ig. 4 is a section on the line 4-4, Fig.3; Fig. 5 is an elevation of the valve operating mechanism, as viewedfrom the left in Figs. 2 and l, with certain parts omitted; Fig. 6 is'adetail perspective view of the operating member detached.

12 denotes a'body having a central longitudinal gas passage 13 andprovided at its upper end. w th a threaded nipple 14 for the attachmentof the burner proper (not shown) and at its lower end with a similarthreaded nipple 15 for connection with the gas supply pipe, as bv meansof a unionor threade sleeve couplin 16.

17 denotes'aninclosing shell or casing suitably held in place on thebody 12, as by having a portion clamped between the union 1G and ashoulder 18 on said body. 19 denotes a passage in the body 12 leadingfrom the main gas passage 13 below or in advance of hereinafterdescribed, and communicating with the pilot tube.

, 20 denotes a screw constituting a valve for controlling the passage ofgas to the pilot tube. Said pilot tube com rises a section 21,permanently secured within a bore 44 in the body 12, and a detachablesection or pilot tube proper 22, said sections being connected by a.sleeve 23 permanently secured to the section 22 and fitting the end ofthe section 21,

24 denotes the main gas controlling valve or cook, said valve comprisinga tapered plug held in a transverse tapered herein the body 12 by ascrew 25 and Washer 26. The valve or plug 24 is arranged with its axistransverse to the axis of the gas passage 13 and at one side thereof,and is provided with a'number (preferably greater than two and hereinshown as three) of communicating, radially arranged ports '27, as shownmost clearly in Fig. 3, said ports forming equal angles with oneanother. The location of the axis of the valve 24 and the arrangcment'ofthe ports 27 is such that two of these ports will registersimultaneously with the upper and lower portions of the gas passage 13,respectively. As shown in Fig. 3 the valve 24 is in a position to permitgas to fiow through the passage 13 to the burner. If the valve be turnedthrough one sixth of a complete rotation the ports 27 will be moved outof register with the passage 13 and the gas will be turned off. Byturning the valve through a further one sixth of a rotationcommunication between the ports 27 and gas passage 13 will again beestablished and the gas will be turned on. It will be seen that thelocation of the valve 24 and the arran cment of its ports is such thatonly one SlXlfil of a complete rotation of said valve is necessary inorder to turn the the controlling valve or cook,

gas. on or oil, and that by increasing the number of ports the necessarymovement of the valve at each operation may be corre spondinglydecreased. It will also be ob- .served that by reason of the passage 19in advance of the valve 24:, the flow of gas to the pilot tube,controlled by the screw er vaive 30 the reduced Uiid if Y iter-ciochm soas to (urn (iii and u; M
